This could be interesting to see how this plays out. I suspect it’s really the motorcyclists insurance company suing to reclaim what it paid out to the rider in hospital fees etc.

A US motorcyclist has filed a lawsuit against General Motors, accusing one of the manufacturer’s robot-operated vehicles of “negligent driving”.

California man Oscar Willhelm Nilsson claims he was travelling down a San Francisco street last month when a Chevy Cruise aborted a lane change and swerved into his lane. The car struck him, “knocking him to the ground”, in an accident that left him injured and unable to work, according to the suit filed in US District Court in San Francisco this week.

The Cruise involved in the accident with Nilsson was operating in self-driving mode at the time of the accident, the suit alleges, but a backup driver was sitting in the front seat of the vehicle with his hands off the wheel.

A San Francisco Police Department report, however, puts the blame on Nilsson. According to the report, Nilsson tried to pass a vehicle before it was safe.

Nilsson’s suit – seeking damages exceeding US$75,000 (NZ$102,000) – is one of the first involving an autonomous vehicle. Though manufacturers say self-driving vehicles will dramatically reduce traffic accidents and motor vehicle fatalities, experts are already warning that there will probably be many more accidents involving robot-operated cars, a type of accident that raises unresolved questions about responsibility and restitution.

As of last week, the California Department of Motor Vehicles lists 54 autonomous vehicle accident reports dating to 2014, most of them minor accidents in which other drivers were at fault. Two Teslas were involved in separate crashes in California last week. Both drivers claimed that the vehicles were on autopilot, a feature that gives the vehicles semi-autonomy but still requires the driver to be responsible for the car.

A Model S driver who ignored numerous warnings inside his Tesla was killed in an accident in 2016. A US National Transportation Safety Board report said the driver was overly reliant on the vehicle’s autopilot before his fatal crash.

But in future wrecks, experts say, manufacturers could see their liability increase.

In a report filed with the California DMV, GM disputed Nilsson’s account of the accident.

“As the Cruise AV was re-centring itself in the lane, a motorcycle that had just lane-split between two vehicles in the centre and right lanes moved into the centre lane, glanced the side of the Cruise AV, wobbled and fell over,” the report claims, noting that the Cruise AV was travelling with the flow of traffic at 12mph (19kmh) and the motorcycle was traveling at approximately 17mph (27kmh).

The report states that accident resulted in a “long scuff on passenger side of the vehicle”.

“The motorcyclist was determined to be at fault for attempting to overtake and pass another vehicle on the right under conditions that did not permit that movement in safety,” the report says, adding that Nilsson claimed he had shoulder pain.

Reached by email, a GM spokesperson said safety is the company’s “primary focus” during the development and testing of self-driving technology.

“In this matter,” the spokesperson added, “the SFPD collision report stated that the motorcyclist merged into our lane before it was safe to do so.”

The suit arrives on the heels of GM’s announcement that the company has submitted a petition to the US Department of Transportation this month asking for permission to deploy self-driving Cruise AVs. A fourth-generation autonomous vehicle based on the Chevy Bolt EV, the vehicles lack a steering wheel, pedals and human backup drivers.

The manufacturer is touting the vehicle as the world’s “first production-ready vehicle” built with the sole purpose of operating “safely on its own with no driver”.

GM – already testing driverless vehicles in San Francisco and Phoenix – is one of several companies testing level 4 vehicles – those that are autonomous to a degree. A California-based autonomous vehicle start-up called Zoox and Alphabet’s Waymo have also tested level 4 cars.

He said the police report stated that the AV driver saw Nilsson before the crash, but didn’t have enough time to grab the wheel and swerve.

“Absolutely we dispute it,” he said, referring to GM’s side of the story. “As far as the technology is concerned, I’m troubled that GM shifted the blame to my client. The manoeuvre by the autonomous car was unpredictable and dangerous.”
